Sparkle on Friday made official its latest graphics card - the Calibre X260/X260 HM. The card uses 55nm GeForce GTX 260 GPU for base model, but adds bumped clock speeds, custom black PCB with enhanced GPU and memory power circuitry, solid capacitors and a custom dual-slot cooler. A 448-bit memory interface and 896 MB of GDDR3 memory are used to finish the whole picture. Sparkle bundles the card with its own SPA Tune, a software that controls the card's clock speeds. It provides three modes - overclocking mode (648 MHz/ 1998 MHz), standard mode (576 MHz/ 1998 MHz), and green mode (400 MHz/ 600 MHz). You can switch between the three modes whenever you want.
